IMPROVEMENT IN CHURN-DASHERS.

Specification forming part of Letters Patent No. 167,5] 2, datedSeptember 7, 1875 application filed May 22, 1875.

, same, reference being had to the annexed drawings making a part ofthis specification,

. and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a vertical centralsection of a churn, showing my dasher, and Fig. 2 is a vertical centralsectional view of my dasher.

This invention has relation to improvements in churn-dashers, wherein anumber of perforated blades are secured to a frame at the end of adash-rod; and the novelty consists in the construction of the dasher, aswill be hereinafter more fully set forth and claimed.

In the annexed drawings, A designates a preferably rectangularchurn-tub, having a detachable lid, B, through which is cut a slot, a,terminating in a cup-shaped circular en largement, I), through whichslot is passed a rod, 0, operated by means of a vertically-vibratinglever, D, fulcrumed at c to an inclined standard, E, rigidly secured asto its lower end to the tub, and stayed, as well against lateral asoutward displacement, by a bracket, d. Rod 0 is mortised into thecross-bar e of an H-shaped frame, F, the end bars 6 of which areprovided with ledges f, the one above the other, which are cut away ateach end, forming inclined recesses g, as shown in figure. D Drepresent, preferably, perforated wooden dashers or beaters, which arejournaled in pairs, and one above the other, in end bars 6, at each sideof cross-bar 6. These heaters are so journaled in frame F that they willautomatically gravitate into an inclined position, their angle ofinclination in relation to bar 6 being about forty-five degrees, andthey are prevented from further gravitating by the abutting of theirupper edges against the correspondingly beveled or inclined ends ofledges f. They also vibrate upward into a horizontal position againstthe under side of the said ledges, striking against which, they will beprevented from further upward movement.

When the churn is in use, and butter is in process of being made, eachdownward movement of the dasher will cause beaters D D to vibrateupward, owing to the resistance opposed to its descent by the cream inthe tub, into a horizontal position, and will cause the currents ofcream to pass rapidly through the holes of the lower wings or blades D,striking violently against the upper beaters D, and then rush throughthe perforations therein, thus breaking up the butter-cells rapidly andeffectually through the hammering action thus produced. In raising thedash, the breakers D D are thrown into the inclined position shown inFig. 2, allowing the dasher to ascend with but little labor, and yetmaterially aiding the butter-making process by throwing the creamviolently against the cross-bar e, reboundin g from which it will passsuccessively through the upper and lower beaters. The frame-work of thedasher, at all points where it is in contact with the churntub, isbeveled, thus doing away with all suction and allowing the dasher towork freely and easily.

J represents a turn-button pivoted to the under side of cross-bar e insuch a manner that when it is turned crosswise to the said bar it willoverlap the lower wings or breakers D, and will hold them rigidlyagainst vibration. By this means the flat surface of these wings will bepresented to the cream, both during the ascent and descent of thedasher, the upper wings opposing their flat surfaces only during thedescent. I sometimes use this button to limit the upward vibration ofthe lower wings, by allowing them to gravitate to their full extent andthen turning the said button crosswise to bar 6. In this position thelower wings will abut against the beveled ends of the said button, andthey will have a minor degree of vibration, with relation to the dasher,well suited for effectually breaking up the butter-cells. When thelowerdashers are allowed to have their full swing, button J acts as a bumper,and prevents the more fragile portions of the dasher from strikingagainst the bottom of the churntub and being broken.

tion in gathering the butter, while the upper set is inclined, causingthe general current of cream to flow toward the center in removing thedasher from the churn in gathering the butter, substantially asdescribed.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
